NY Times - Confidence Intervals!

New York Times, 12/27/97, page D2 "Worries About the Rush to Mutual Funds"

After reporting the results of a study about the percent of American
Households owning sock funds, the article stated:

"The survey had an error rate of 2 percent, meaning that 95 times out of 100
a similar survey would produce results within 2 percentage points of the
current data."

1) It is great that a popular paper is trying to explain the meaning of the
results of a study.

2) Am I right that this is not a correct interpretation of a confidence
interval? [if they changed "within 2 percentage points of the current data"
to "within 2 percentage points of the actual data" it might be a reasonable
attempt to explain a difficult concept]
